wardly to lie against the inner faces of end walls ,l 3 and by foldingmarginal extensions or aps 8 3 Claims.

This invention relates toA containers, particu-` larlylshipping cartonsof the type comprising a tray member and a cover member telescoped oversaid tray member. The invention has for its principal object to providea simple and economical carton of the above type wherein the covermember cooperates withthe tray member to firmly secure said memberstogether and to seal. strengthen and'stien the carton. The inventionconsists in providing two opposite side walls of the cover member withmarginal aps that are folded inwardly towards one yanother and`adhesively secured atwise to the bottom of the tray in edgewiseabutting relation to one another and to the other two sides of saidcover member. The invention also consists in the conof said end wallsdownwardly and inwardly against said inwardly bent side wall flaps. Thecorners of the cover member B are formed in a similar manner; that is,by providing the end walls 6 with marginal flaps Ill that are rebent onthe inner sides of said walls to hold the inwardly bent end flaps 9 ofthe side walls 5 between said end walls and the foldedmarginal iiapsthereof.v

The cover member B fits snug1y ,over theitray member A of the carton;and the sidefwalls of said cover member have marginal flaps orextensions II 'that are folded inwardly upon the exstruction,lcombinations and arrangements of I' parts hereinafter described andclaimed.

In the accompanying drawing, which forms part of the specification andwherein like symbols refer to like parts wherever they occur,

Fig. 6 is a central longitudinal section through the end portion of thesealed carton on the line 6-6 in Fig. 1; and

' Figure 7 is a cross-sectional view, similar to Fig. 5,- showing amodified cover member.

M y shipping carton comprises an inner or-tray member A and an outer orcover member B telescoped over said tray member, each of said membersbeing made of bendable material, such as ber or corrugated board. Thetray member is made from a blank which is folded up around the bottom Iof the tray as a basis to form side walls 2 and end walls 3; and the top4, side walls 5 and end walls 6 of the cover member are like- Wiseformed from a similarly folded cover blank. The corners of the tray areformed by folding end flaps or extensions 'l of the side walls 2 inposedsurface-of the bottom I of said tray member and are adhesively orotherwise rigidly. secured iiatwise'thereto, said aps being preferablyin edgewise abutting relation along the longitudinal center line Iof thecarton. If desired, the joint between theabutting edges of the side wallflaps I I of the cover member B may be sealed by means of a strip I2 ofgummed tape. As shown on the drawing, the end walls 6 of the covermember B are of slightly greater depth than the side walls 5 thereof sothat the side wall flaps II fit between and are disposed in endwiseabutting relation to the projecting folded edges of said end walls.

The articles or materials that are to be packaged are placed in the traymember A of the" carton and the cover member B is then telescoped oversaid tray member, after which the assembled members are inverted and theside marginal flaps II of said cover member folded down upon andadhesively secured ilatwise to the bottom portion of the inverted tray.By this arrangement, the folded side wall flaps II of the cover member Bserve to lock the tray member A therein; they also serve as sealingmembers for the carton; and they also function as struts and tie membersthat cooperate with the bottom portion I of said tray member tovstrengthen and stiffen the carton both longitudinally and transversely.Thefolded marginal edges of the end walls 6 of the cover B terminatebeyond the plane of the bottom I of the tray member B; and the foldedside wall flaps I I of said cover member t snugly between said end wallsin endwise abutting relation thereto, thereby 'resisting any tendencyfor the side cover flaps to slide longitudinally relative to each otherand to the tray member and throw the carton out of square.

Obviously, the side marginal flaps II of the cover member Bvmay bespaced apart along their adjacent side edges and held in place by meansother than adhesive, Also, as shown in Fig. "I. said cover member may beprovided with wide side marginal flaps Ha which are lapped one over theother and adhesively or otherwise held in place, Also, the endconstructions of the tray member A and the cover member B may be variedWithout departing from the invention.

What I claim is:

1. A carton comprising a tray member and a cover member telescoped oversaid tray member, said cover member having aps along the margins of theside walls only'thex'eof that are folded over the bottom of said traymember and are adhesively held in place, said cover member having endwalls that terminate beyond the bottom of said tray member substantiallyush with the exposed faces of the folded side wall aps of said covermember, said folded side wall flaps of said cover member extendingcontinuously from end wall to end wall thereof between and in endwiseabutting relation to the projecting portions of said end walls. 2. Acarton comprising atray member and a hesively secured atwise to thebottom of said tray in sidewise abutting relation to one another, saidcover member having end walls that terminate beyond the bottom of saidtray member substantially ush with the exposed faces of the folded sidewall iiaps of said cover member, said folded side wall naps of saidcover member extending continuously from end wail to end wall thereofbetween and in endwise abut- 10 ting relation to the projecting portionsof said cover member telescoped over said tray member.

said cover member having flaps along the margirlsl of the side wallsonly thereof that are folded inwardly towards one another and are adendwalls.

3. A carton comprising a tray member and a walls that terminate beyondthe bottom of said v tray member substantially flush with the exposedface of the outermost folded side wall iiap of said cover member, saidfolded side wall 11ans of said cover member extending continuously` fromend wail to end wall thereof between and in endwise abutting relation tothe projecting portions of said end walls.
